Element, panel and system for collecting and concentrating direct solar radiation by means of panels of collection and concentration elements granted freedom of movement in daily and seasonal solar tracking. These elements are formed by a primary direct-radiation concentrator lens. The element has hollow compartments containing a specific fluid at a specific pressure. In the lower part, a secondary lens and/or an internally reflective conical element allow/s the introduction of the radiation in parallel in conduits or an optical fibre or irradiation on radiation-conversion systems. Movement of the element arises from heating and pressure of the fluid in the side compartments. This pressure is communicated to the shafts via pistons such that the rotational movement of the element, seeking the best position for optimum focusing on the secondary lens, is generated. |
